The incident began as an argument inside the Sports Corner Café at Second and K streets about 9:40 p.m. Monday, as tens of thousands of people gathered to celebrate New Year's Eve.

Police said it is believed Amber Scholz instigated the fight that her husband and Montoya were involved in before shots were fired.

Montoya is in police custody recovering from multiple gunshot wounds at an undisclosed hospital.

Gabriel Cordova and Daniel Ferrier, a bouncer at the bar, were killed in the shooting.

Isaiah Cordova said his father and stepmother, Christina, had gone to the bar to celebrate New Year's Eve.

Cordova said that according to family members who were at the bar with his parents that night, his father spilled a drink on a woman, who was friend's with Montoya. Police confirmed that the argument started over a spilled drink.

Investigators said Montoya then shot and killed Gabriel Cordova and wounded Christina Cordova in the lower body.

Police said Ferrier was shot while trying to break up the fight.

Stephen Walton, an armed security guard who was working at the bar, was also wounded during the shooting.

Walton was at UC Davis Medical Center in Sacramento recovering from his wounds.

Scholz and Fowler-Scholz are scheduled to appear in court on Tuesday.
